Domino's Kobe Beef Steak Pizza (All Rights Reserved)

In the land of fast food foie gras burgers, Whopper buffets and dyed black burger buns, comes the latest extreme food from Domino's in Japan: a pizza topped with Kobe beef for the price of about $66.

The world's largest pizza delivery service recently launched a Kobe Beef Steak Pizza topped with potato, onion and steak sauce and the star ingredient -- Kobe beef, known worldwide for its superior flavor, texture and marbling thanks to pampering breeding methods.

Staff at the English-language news site RocketNews24, meanwhile, decided to take the novelty pizza for a test drive and "pooled their New Year's money" together to spring for the 5,800 Yen ($66 US) meal. Reviews are mixed, with some of the taste testers describing the unlikely combination "spot-on," "sublime" and "pizza ecstasy."

While the generous chunks of fatty meat were appreciated by some, others, however, found the quantity and richness of meat to overwhelm and dominate the flavors of a classic pizza.

"On a negative note, with the beef being the focal point of the pizza…it actually detracts a little from the traditional notion of what makes a good pizza."

The pizza will be available for a limited time until mid-January.

Meanwhile, Japan is home to a slew of fast food innovations. Wendy's, for instance, topped their burgers with foie gras, Burger King offered customers an all-you-can-eat buffet of Whoppers and sandwiches topped with black buns.
